THOMAS J. A. MACDONALD, DETROIT, MICHIGAN.

SALE-SLIP.

SPECIFICATION forming part of Letters Patent No. 407,299, dated July 16,1889.

Application filed June 19, 1888. Serial No. 277,549. (No model.)

To all whom it may concern:

Be it known that I, THOMAS J. A. MAC- 2 DONALD, a citizen of the UnitedStates, residing at Detroit, county of WVayne, State of Michigan, haveinvented a certain new and useful Improvement in Paper-Clips; and Ideclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and 'use the same, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to paper-clips, and is particularly designed to beused in connection with sale-slip pads, memorandum-books, &c., whereinthe quantity of slips or sheets is of substantially uniform thicknesswhen grouped or blocked.

In the drawings, Figure 1 is a cross-sec- I tional view of my improvedclip as it would appear attached to a sale-slip cover and with a bunchor block of said slips in place. Fig. 2 is a perspective view of saiddevice.

In the manufacture of sale-slipsithas been customary to make them up inblocks of a given number of sheets, and then to provide the clerk orsalesman with a cover to which the blocks or bunches may be attached andrenewed as often as new blocks or bunches are required; and thisinvention has to do with the production of a convenient and improvedcover for the purpose.

The object of this invention is to provide a stiff cover, if a cover isemployed, with a clip rigidly attached to the cover and at the same timestrong and not likely to get out of order. Said clip is devoid ofsprings and suited in each case to bunches or blocks of a given numberof slips or sheets, and therefore of substantially uniform thickness.

In the drawings, A represents a sale-slip or memorandum-cover providedwith my improved clip. The clip consists of a lower plate B, rigidlyattached to the cover A, and is turned up at b to form a heel-plateagainst which the sale-slips E abut, thus squaring the same if they areunlocked. The plate B is also provided with side pieces 1), serving asjournals for the jaw D..

the jaw D is turned down upon the slips,

causing the edge (Z of the jaw to impinge firmly against the paper andcompress it between said edge d and the heel-plate b, as shown at (1,thus holding the paper firmly in position.

The slips used are of any ordinary form; but the kind which I usuallyemploy are those shown in the drawings, which are perforated at e and e,and in which a carbon sheet is located beneath the clip on top of theslips or block, and the farther ends folded with the cover over upon thecarbon sheet. The heel cl may be dispensed with, and so the plate B mayengage either above or below the cover, and may extend clear across thecover or only a little distance at each corner.

I prefer that the under edge of the jaw D shall be smooth rather thanprovided with teeth, for teeth atthis point are apt to so perforate thecarbon and adjacent sheet as to render them easily torn loose and sobecome lost, or at least separated from the balance of the sheets; butit may be toothed or serrated without departing from my invention.

The back or cover may be dispensed with and the clip be employed-simplyas a separate appliance for grasping the ends of a bunch of slips orsheets of paper or for holding a block of paper. So, also, the cover,instead of being of thick stiff material, may be simply a sheet ofManila or other ordinary flexible leaf of paper or other material. So,also, when a block of paper or slips is used, the clip may serve simplyto bind and holda loose carbon sheet upon the said block.

WVhat I claim is- A paper-clip consisting of a plate B, having anupturned heelplate b and side pieces In testimony whereof I sign thisspecifica- Z), and a, jaw D, consisting of a strip of sheet tion in thepresence of two witnesses.

It is hereby certified that the title of the invention described inLetters Patent No. 407,299, granted July 16, 1889, upon the applicationof Thomas J. A. Macdonald, of Detroit, Michigan, should have beenwritten and printed Paper Clips instead of @fale- Slips, and it isfurther certified that the said Letters Patent were erroneously issuedto said Thomas J. A. Macdonald, that said Letters Patent should havebeen issued to Hurlburt, Frink d2; 00., said Hurlburt, Frink & 00. beingassignees of the enti e interest in said invention, as shown by recordof assignments in this office; and that the said Letters Patent shouldhe read with these corrections therein that the same may conform to therecord of the case in the Patent Office.
